Flexaust 3504040000 Vacuum Duct Hose 4 in Id 25 Ft Pvc

Product Description

The FLEXAUST 3504040000 is a PVC vacuum duct hose engineered for light-industrial and commercial ventilation applications. Constructed from polyvinylchloride with a crush-resistant wall, it measures 4 inches inside diameter and ships in a 25-foot length. The hose handles a vacuum rating of 14 inches Hg and a maximum working pressure of 16 psi, making it suitable for moderate-duty air-movement and fume-extraction systems. Wall thickness is 0.032 inches, contributing to flexibility while maintaining structural integrity under suction loads. Licensed HVAC technicians, sheet metal contractors, and industrial maintenance crews are the typical installers.

This hose is designed for conveying air, dust, and fumes in ducted vacuum and ventilation systems. Its operating temperature range of 20 degrees F to 160 degrees F makes it appropriate for both unheated equipment rooms and warm process environments. The 4-inch ID is a common size for portable industrial vacuums, dust collectors, and fume-extraction hoods found in light manufacturing, woodworking shops, and mechanical service facilities. The black PVC construction resists light abrasion from dust-laden airstreams.

Key Features

• Crush-resistant PVC construction maintains hose shape under vacuum load up to 14 inches Hg
• 4-inch inside diameter fits standard dust collector and industrial vacuum ports
• 25-foot length reduces the need for couplings in single-run installations
• 16 psi maximum working pressure supports both pressure and vacuum service
• Operating range of 20 degrees F to 160 degrees F suits a wide range of service environments
• 0.032-inch wall thickness balances flexibility with durability

Compatibility

Designed as an OEM-style replacement or new-installation hose for 4-inch ducted vacuum, dust collection, and fume-extraction systems handling air, dust, and fumes.

Installation Notes

Installation is typically performed by HVAC technicians or industrial maintenance mechanics. Shut down and de-energize any connected blower or vacuum equipment before attaching or removing hose sections. Secure hose ends with appropriate clamps or couplings rated for the system pressure and vacuum levels. Avoid routing the hose near surfaces that exceed 160 degrees F or below 20 degrees F to stay within rated temperature limits.
